CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) DIP SW setting: Check that the switches are set to ap-
propriate positions.
3) Power input voltage: Check voltage across the terminal
11 – 12 with a multimeter.
4) Input: Check that the input signal is within 0 – 100% of
full-scale.
5) Output: Check that the load resistance meets the de
-
scribed specifications.
I/O RANGING & FINE ADJUSTMENTS
After the DIP SW setting is complete, set up the precise
input and output range using the front control buttons. Be
sure that the front control button function is enabled with
the DIP switch setting.
The front LEDs’ colors and blinking patterns help you to
easily identify the transmitter’s status and confirm the set-
up actions in each step of Calibration Modes. Please read
the following explanations referring to “Calibration Flow
Chart” below.

When you set 0% or 100% input/output ranges,
keep pressing UP or DOWN button until the
LD1 blinks for approx. 2 seconds and turns off,
which indicates the setup is complete.
When you release the button, the LD1 is returned
to ON.
If the LED does not change, the entered level may
be inappropriate, i.e. out of usable range.
